In molecular communication (MC), biochemical signals (usually small particles) create a gaseous medium to make the communication. It is usually compared with radio communications. MC signals are mainly biocompatible as they consumes very small energy particles. It mainly wants to interface with mobile networks and the Internet, which are more challengeable [1]}. Quantum communication (QC) is one of the most secure forms of communications. We encode the information in the quantum state by using photons or quantum particles. The QC has a huge potential in long-distance communications [1]}. Therefore, both MC and QC can be effective in 6G [3]}.
